from what i understood in physics class (very little), there's no way the plane can take off, the plane will have no net movement in the forward direction. with no forward movement, it cant get any air to run over the surface of the wing to create lift. the wheels have nothing to do with the flight, if the plane itself isnt moving, it cant fly...i could be wrong, but this is how i look at it...

the plane is not driven by the wheels.... its driven by air movement by the engines.... the air WILL push the plane forward, it will move forward no matter what the wheels do!! I say it will take off.... Dosent matter whats going on with the wheels....

the plane is not driven by the wheels.... its driven by air movement by the engines.... the air WILL push the plane forward, it will move forward no matter what the wheels do!! I say it will take off.... Dosent matter whats going on with the wheels....

if the wheels are not free spinning then the plane will fall off the back of the conveyer....SO IT DOES matter what the wheels are doing....the wheels may not be what drives the plane foward but if they are not spinning then it is like the breaks are on.......

heres my take on it

Invision this,
Put a toy car on a belt sander. The car is the jet, the sander is the conveyor. Holding it in place on the sander is the push of the jet engine. When a real jet takes off do the wheels turn? So are the wheels on the car. If you push the car forward on the belt the the engine would be not at the same speed as the conveyor. Therefore the jet is not making any forward progress, so lift isn't being made around the wings for it to take off.
Well that settles this one, next question please

Thats exactly what i was trying to say, but you made it make more sense...thanks man

sooo Chris

What do you do Chris sit back & boggle your mind with questions like this one? Heres something a little more simple & fun. Tie your shoe. Now tie it again, only make your right hand do what your left hand just did & left hand do what your right hand did. Basicly switch roles of your hands. See you've been tying your shoes the same way for years know you don't think about it you could even tie them in the dark if you had to but now you have to think about it, it's kind of like learning all over again. Most people I've tryed this on can do it but it takes time tying is all.
Merry Christmas everyone

When a real jet takes off do the wheels turn? So do the wheels on the car.

But if you push the car foward once you have set it on the belt the car continues on and that is even with the belt moving faster then the speed of the car, why you ask? Because your hand is like the engines on the plane, both car and jet are being put in motion by a force that is not transmited to the tires which are setting on the belt.

There fore the jet will continue with its foward motion even with the belt spinning at the same or faster rate then the jet is moving.

Get your belt sander out and try it, place your kids car on it and see if you can roll it on it. You will be able to roll you car against the rotation of the belt with out have into push it any faster then if sander was turned off. The only thing that would be different with the sander off or on is the speed at which the tires turn.

Like you said, "Well that settles this one, next question please".

Yeah I finally got tired of thinking and looked it up... rack one up for Dodge!

You have a 747 sitting on a huge conveyor belt. This conveyor belt is controlled by a computer that precisely matches the speed of the conveyor to the speed of the jet, only going the opposite direction. When they throttle up, will the jet be able to take off?

yes it will take off because it isn't pushing against the force of the conveyor it is pushing against the force of the air.
